摘　　要：通过对双馈风力发电机绝缘结构的验证,证明了所提供的绝缘结构满足双馈风力发电机使用需求。双馈风力发电机转子线圈承受变频电压的冲击,现阶段的转子耐电晕云母带都是采用进口云母带,价格高昂,为此需要考虑使用国产耐电晕云母带代替,研究国产耐电晕云母带在高频高频脉冲的条件下的使用寿命,是否能够满足电机寿命要求,以期能进一步降低电机批量化生产后的成本。This paper proves that the insulation system of doubly-fed wind generator can meet operation requirements through the inspection of its insulation structure.The rotor winding of doubly-fed wind generator withstands the impact of variable-frequency voltage.At present,the corona resistance mica tape used on rotor is imported from abroad,so we suggest to replace it with the mica tape produced by domestic factory due to its expensive price.This paper researches whether the working life of domestic corona resistance mica tape under high-frequency pulse condition can meet the life requirements of motor,so as to reduce the cost of mass motor production further.
